Application filed September 3, 1915. Serial No. 48,813.

To all whom it may concern:

Be it known that I, CHARLES T. RAY, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented certain ed to exemplify the invention: it beingunderstood that changes in the details may be made without departingfrom the spirit of the invention, or the scope of the subjoined claims.v

Fig. 8 is a detail view of the crank 66 I which forms a member of themeans for adjusting the forward furrow turning-member, showing thereinthe trunnioned bearing for the connecting rod 65.

Fig. 9 is. a rear end elevation of the implement.

The main frame is provided with a straight side member 10 which extendsfrom the front to the rear end of the frame. Its other members may bevariousl arranged to produce a frame which is wider at the rear than atthe front. The frame herein exemplified comprises a longitudinal member11 arranged at the side opposite the member 10 and extendingsubstantially parallel with the latter for. a part of its length andthence extending diagonally toward the front end of the member 10 asshown at 13. The rear ends of the members 10 and 11 are connected witheach other by a transverse member 12. 14 designates a third longitudinalmember. This is arranged between the members 10 and 11 and substantiallyparallel with the member 10. Its rear end is suitably secured to therear transverse member 12. These members preferably are formed ofchannel irons. The front ends of the members 10, 13 and 14 are securedto a uniting member 15, which extends for- Wardly and also upwardlytherefrom. This member is preferably a strong casting having horizontalflanges 15, upon which the frame members 1O, 13 and 14 respectivelyrest, and vertical webs 15 against which said members respectively lie,suitable means being employed to secure the contacting parts of themembers together. The uniting at the front end with a sleeve 15surmounted by a plate 15 A designates a large traction wheel of suitableconstruction, which is arranged between the members 10 and 14 and at orabout the longitudinal center of the implement. Tminediately in advanceof this traction wheel there is a forward furrow turning member B of anysuitable kind, the one herein shown being an ordinary single moldlboardplow. This forms a furrow on the bottom of which the action wheel runs.At one side of the frame there is arranged a suitable wheel C whichtravels upon the unplowed land and is suitably mounted to be verticallyadjustable in accord with the depth of the furrow in which the tractionwheel runs, any of the usual or suitable means for such adjustment beingemployed.

At the front end of the implement there is a guide wheel D. This guidewheel is offset from the line of the forward furrow forming member andtraction wheel A and traverses a furrow, made on the previous travel ofthe implement by a rear furrow forming member E which is disposed at therear of the traction wheel on the side of the line of the traction wheeland furrow forming member B opposite that of the guide wheel.

The traction wheel is a large one and receives motion from an engineofsuitable type which is geared thereto and is carried by the frame ofthe implement. The engine is illustrated diagrammatically at F and isshown as being mounted on a bed plate 19 supported by the members 11 and1%. The engine employed is preferably of the gasoline type and in suchcase, a suitable radiator, clutch etc, not necessary herein moreparticularly to set forth, will be provided in practice Any suitablemeans for transmitting the power of the engine to the traction wheel maybe employed, one such being herein exemplified. The means herein showncomprises a spur gear 20 which is suitably secured to the wheel A andhas its teeth engaged by a pinion 22 mounted on a transverse shaft 23which carries a gear 24. which meshes with a gear 25 mounted on theengine shaft 26.

The points or cutting edges of the front and back furrow forming membersB and E are at the same level, and the lower surfaces of the guide wheelD and traction wheel A run upon the bottom of the furrows made by saidmembers; As already stated, the traction wheel traverses a furrow madein the same travel of the implement by the furrow forming membersimmediately in front of it, while the guide wheel is arranged in advancebut to one side of the line of the front furrow forming member andtraverses the furrow made on the previous travel of inane-ca coming anytendency for the frame to tilt the implement by the rear furrow fox-minmember, as clearly shown in Fig. 1. A fur row wall is thus presentedagainst whic the guide wheel may bear and which may b used as a guide inthe manual guidance 0 the implement. A further important ad} vantageresults from the use of furrow forming members and wheels arranged inthe lines herein set forth, as forces are thereby brought into operationwhich overcome an objectionable extent of side draft which would tend tounnecessarily strongly press the guide wheel against the solid wall atone side of the furrow or the loose dirt at the other side of thefurrow, such as occurs when furrow forming member or members arrangedonly at the front or only at the rear of the traction wheel, areemployed. This unnecessary side draft introduces an unnecessary amountof friction for the engine to overcome.

Moreover, the employment of furrow forming members arranged as hereinshown, reduces the number of travels of the implement required inplowing a field: the setting of the furrow forming member so that itspoint or cutting edge is level with the bottom of the traction wheelproduces a furrow with a smooth even bottom by overforward or back,which tendency, unless corrected, would produce an uneven furrow: andthese smooth even bottoms provide most desirable bases for the tractionwheel and guide wheelto traverse. When single moldboard furrow formingmembers, such as herein exemplified, are employed, they are set out ofline with each other a distance equal to the width of the furrow whicheach is to make, as shown in Fig. 2, thus giving sufiicient side draftto hold'the inner edge of the guide wheel against the solid Wall of thepreviously formed furrow with strength suiiicient for the purposeintended to be secured. but with no undue force, that is, with no forceunnecessary in proper plowing. The forward furrow forming member isarranged so that it will plow a stri one side of which is substantiallyin line with the outer side of the traction wheel and th other side ofwhich is in line with the inner side of said wheel, whilethe rear furrowforming member is arranged to plow a strip commencing substantially inline with the inner side of the traction wheel.

The guide wheel D is connected with means whereby the implement may beguided manually, preferably from a seat 27 at the rear of the implement.This seat 27 is mounted on the upper end of a seatcarrier 28, soarranged that the seat is disposed substantially in line with thestraight side member 10 of the frame admenace jacent to the line ofwhich member the guide wheel D and the forward forming member B arearranged. Accordingly, the operator has an unobstructed view of saidguide wheel and furrow forming member and is thereby enabled to betterguide the implement in a straight path. The wheel D is journaled in thelower end of a yoke 30 which is provided with a vertical pivot 31mounted in the sleeve 15 at the front end of the casting 15. Themechanism by which this wheel is turned by the operator to guide theimplement preferably comprises a gear 32 which isvfixed to the-pivot 31above the plate 15. This gear is engaged by a worm 33 mounted on a.shaft 3 1 from which an operating rod 35 extends rearward, the rear endof the operating rod having suitable means, as a handwheel 86, arrangedconvenient, to the operator on the seat 27. When the rod 35 is turned bythe hand wheel, motion will be cOmmunicated to the pivot 31 through theshaft 34, worm 33, and gear 32. Conversion of the wheel D from aman-operated wheel to a casteringwheel constitutes one of the im-'portant features of the present invention. When the particular guidingmechanism herein set forth is employed, the worm 33 and its shaft 3stare preferablycarried by a cap 37 which serves also to house the gear 32and is' mounted for lateral adjustment bodily on the plate 15 thislateral adjustment being such as to carry the worm out of or into meshwith the gear 32. The cap is guided in its movements, preferably bybolts or pins 38 which extend through openings 39, as shown in Fig. 3.The

niove'ments or adjustments of the cap are eiected by means which may beoperated fromthe seat 27. This means, in the herein-exemplified form ofthe invention. com pris'es an operating lever 40 which is pivoted at 41and is provided with a rod 4'2 whose forward end is connected-roan armor crank 13 having a cam 15, the crank and cam being loosely mounted,preferably in the reduced upper end 44 of the pivot 31. The cam isarranged in an opening 46 formed in the cap 37. The correlation of theparts is such that the cam 15 engages the walls of the opening '46 andwhen turned, by the forward or rearwardmovement of the rod 42, operatesto shift the cap 37 to one side or the other according to the directionof the turning move? ment given the cam. it being neted that in theherein exemplified form of the invention the opening 46 is approximatelyrectangular and that the cam 45 engages angularly-disposed wallsthereof, whereby the cap is, shifted with a minimum extent of movementof the rod 4:2 and lever 40. Suitable provision for locking the leverand hence the cap, in adjusted osition, are provided: the means hereinexemplified comprising a-latch, indicated at 4-7 in Fig. 9, the saidlatch being connected with a hand piece 48 (Fig. 6) and being arrangedto engage any one of the teeth 49 of a segment 50. It is. only necessarythat there be two teeth 49 in the-segment, .as there are only twopositions to which the cap need be adjusted.

the'wheel C as an axis, the power being applied to the traction wheel.It will be observed tlrat the lower end of the yoke 30 is inclinedrearwarchso that the center of the wheel D is out of line with the pivot31, to facilitate the metering operation of the wheel. The locking ofthe land wheel C may be accomplished by any suitable braking meansoperable from a point within convenient reach of the operator on theseat "27. As the particular means for the purpose is not essential tothe invention 1 do not consider it to be necessary to enter into anydetailed explanation, but the mechanism herein described comprises,speaking generally, a transverse shaft 51 suspended in suitable bearingsprovided on the frame and having a down-turned cranked end 52 near theseat.

The wheel (1 is provided with a drum 53, and

suitable brake shoes, shown at 54, are arranged to engage the drum :byappropriate movement of the shaft 51, the shaft 51 being connected withthe brake shoes by means which includes a rod 55 and suitableconnections between the rod and the shoes.

The furrow forming members are independently adjustable relatively tothe frame Further, the adjusting means devised by me and shown in theaccompanying drawings is of such nature that the furrow-tunung membersmay be set to work at a. predetern'iined depth prior to the commencementof the plowing operation and when in operation will beyieldablysupported in order that they may ride over'any obstru-ctions and adjustthemselves when depressions or soft spots are reached. Mechanisms havingthe characteristics herein set forth and which, at the same time, are ofmost simple and practicable construction will now be described.

Each furrow turning -member B and E is provided with a vertical standard60 which is mounted for vertical movement within a suitable guidingframe 61 carried by the frame. Each guiding frame preferably hasfriction-reducing rollers 62 engaging the forward and rear edges of thestandard which passes through the frame. The forward furrow turningmember B is operated by a lever 63 which is pivoted at 61 to anappropriate part of the frame and is arranged adj scent to the seat 27,the lower end ofthe lever being connected by a rod 65 with a crank 66projecting from a shaft 67 having a second crank 68 extending rearwardtherefrom (shown in dotted lines in Fig. 6), the second crank having itsrear end connected to a link 69 from the upper end of which a laterallyprojecting pin 70 extends into any one of a plurality of apertures 71formed in the standard 60. It will be noted that when the up er end ofthe lever 63 is pulled backwar the furrowturning member B being assumedto be in working position, the connecting means between the lever andsaid member will be moved in a direction-which raises the member totransport position. In order that the member may be adjusted to workingposition, when the implement is standing on unp lowed land, the crank66, as shown best in ig. 8, has its upper end bifurcated and withinthisbifurcated portion there is disposed a jou-rnaled bearing 72 throughwhich the rod 65 extends loosely. The rod projects forwardly beyond thebearing and its projecting end is encircled by a spring 78, one of whoseends preferably abuts against a stop 74 on the rod and the other ofwhose ends preferably abuts against the forward surface of thebifurcated portion 66 of the crank 66. It will be seen that when theimplement is standing on unplowed land and the lever 63 is thrustforward the rod 65 will be moved through the bearing 72, thereby placingthe spring 73 under tension such that it exerts pressure upon the memberB through the crank 66, shaft 67 crank 68, link 69 and standard 60,which pressure aids the force of gravity in the lowering of the furrowturning member to its working position when the plow enters the land.The movement of the rod 65 relatively to the crank 66, permitted, by theconnection described, enables the lever to be thrust forward to aposition beyond that defined by the engagement of the furrow-turning memher with the land and hence the furI0W-turn-' 65 ing member may be setto work at a predetermmed depth while the implement is menses .fixed inits predetermined position, prefstanding upon unplowed land. A shouldeis provided on the rod to limit move ment of the arm 66 under influenceof th spring and prevent excessive downwar movement of the member B. Thelever i.

erably by a latch 75 (Fig. 7) arranged tr engage any one of the teeth ofa segment 7 6 the latch being preferably operated by means of a grip 77connected with the latc-l by a link 78. The segment 76, instead 0 beingfixed is pivoted, preferably On th pivot 6a of the lever 63, and aspring 79 extends from the segment to an appropriate part of the frame,to which it is secured. In practice, it is preferred to connect theforward end of the spring to a bolt 80 adjustably mounted in aprojection 81 fixed upon the frame member 10, this connection permittingthe tension of the spring 7 9 to be adjusted. It will thus be seen thatwhen the lever is released by disengaging the latch from the segment,the lever may be moved relatively to the segment, to adjust the heightof the forward furrow-turning member relatively to the frame and thatwhen the said furrow-turning member has been adjusted to workingposition and the lever has been locked to the segment, thefurrow-turning member is under the influence of the spring 79 and isenabled thereby to adjust itself automatically to accord with varyingconditions which may be encountered in the operation, such asobstructions, depressions or soft placesthe segment, the lever, and themeans connecting the lever with said member, moving as a unit.

The adjusting mechanism for the rear furrow-turning member E ispreferably substantially like that employed for the forward memlberexcept that the position of the rear member with relation to its 'actuating lever, marked 82, is such that the rod 65 is dispensed with. Inother words, the segment 83 is pivoted and a spring ea extends from thesegment to an attaching means 85 carried by an appropriate part of theframe; the lever has a latch for locking it in various selectedpositions to the segment and its lower end is secured directly to ashaft 86, corresponding to the shaft 67 having a crank 87 with a lateralprojection 88 extending into any one of several apertures proiuded inthe standard 60 of the rear member i E. This standard is verticallyadjustable through an appropriate guide frame 61 having rollers 62arranged to engage its front and rear edges. While this means connectingthe rear furrow-turning member with its adjusting lever does not permita setting of the lever beyond the point defined by the surface of theland, that is to say, while it does not employ any relatively movableconnections between the'lever 82 and the crank 86, it should be notedthat when the rear furaeaeoe row-turning member is so ,as it is normallyin ordinary plowing, in line with the bottom of the traction wheel A,the depth of thefurrow made by it is always the same as that made by thefront plowing element and hence there would be no particular advantagein providing means, such as are exemplified in connection with theforward furrow-turning element, for permitting a movement of theadjusting mechanism beyond that defined by the land when the implementis standing onunplowed land. In other words, the only adjustments neededfor the rear plowing member are adjustments above the plane of the lowersurface for working purposes.

Particular attention is called to the fact thatthe yieldable mountingsfor the furrowturning members not only enables said memto yield toobstructions but. further enables them to adjust themselvesauton'iatically when depressions or soft spots are encountered in suchmanner that the traction of the wheel A is not diminished. l'n plowingwith one furrow-turning member ahead and the other behind the tractionwheel, any depression or soft spot in the land would cause the weight ofone side of the implement to rest on the furrow-turning members-and ifthese members were rigidly sup ported thetraction of the wheel A on theland would .be diminished and said wheel would spin around, because ofits failure to get a firm grip on the land under it. But by the use ofthe springs, the furrow-turning members will yield to the weight imposedon them, thus permitting the traction wheel to get a firm grip on theland under the varying conditions referred to.

It will be understood that the land wheel C is an idle wheel and that itis mounted on a crank shaft 100 having the ordinary, or any suitablemeans, for adjusting it to accord with the depth of plowing, this wheelrunning on the unplowed land while the guide wheel. the traction wheeland the plowing members run in furrows, as hereinbefore explained.

The furrow-turning members, being independently adjustable. one may beset. to

working position and the other in transport position, if required forany reason-when the soil is too hard for both to be used, for example. 7

While I prefer to employ two furrowturning members of the singlemoldboard type, arranged respectively in advance and at the rear of thetraction wheel, I, nevertheless, wish it to beunderstood that I do notlimit myself in all respects to this particular number, type orarrangement of soilturning members.

a It will be noted that the frame has its member 10 arrangedsubstantially in alinement with the longitudinal axis of the implementand that the front member 13 converges forwardly toward the forward endof the member 10, and also that the uniting or connecting member 15 issubstantially triangular in shape andhas its rear portion extendingbetween the members 10 and 13, its said portion being said members.Further, it will be noted that the member 15 extends forwardly from thefront ends of the members 10 and 13 and this forward portion carries thedriving wheel. Still further will it be noted that the frame hassubstantially a trapezoidal shape and that the longitudinal axis of thetrian ilar connecting member 15 lies substantial y in that diagonal ofthe trapezoid which extends from the convergent angle of the members 10and 13 to the angle of the members 11 and '12. By this means the thrustof the guiding wheel is transmitted through the frame members in suchmanner as to take up the stresses incident tosuch thrust in a highlyefficient way. It will also be observed that the quadrant 76 is providedwith a stop TGwhich. when the quadrant is in its normal positioncontacts with the bracket 6a which supports the pivot 64 of thequadrant.
